  wasm: ensure post-linker output is synchronous ESM
  
  This patch fixes wasm backend's post-linker output script to ensure
  it's synchronous ESM and doesn't use top-level await, which doesn't
  work in ServiceWorkers. Fixes #27257.
  
  (cherry picked from commit cccf45da01988801b0c97f7e7ed0160191980226)
